October 2nd. Boy, the date sure creeped up on us, but it's here regardless -- the Samsung Galaxy S II has finally debuted on AT&T. Many of you who've been waiting several months for a subsidized GSM model in the US may find it hard to believe that you're able to head on over to the carrier's site and purchase one for a couple C-notes. Rest assured, we've checked it out ourselves and it's really, really there, waiting for you to click that "add to cart" button. So if the style and carrier fit your fancy, friends, carpe diem.
